This is a photo of a Cudahy produce reefer, circa 1912 or earlier. At the time Cudahy, like most of the large meat packers, used their refrigerator cars to carry and distribute produce and other non-meat products in their refrigerator cars.
That practice was almost entirely an Armour activity, though some of the other packers handled non-meat cargo, as this photo shows.
This was before anti-trust regulations and the Supreme Court forced the large meat packers to divest themselves of many non-meat product lines and properties.
Actually, it was the Federal Trade Commission, not the Supreme Court, that ordered Armour out of the non-meat reefer business, in 1919. By that time, no other meat companies still were operating non-meat reefers.
